What did Paul stipulate about Abraham believing God and our position?
Paul stipulated that as Abraham believed God, so is where we are. Abraham's faith was that which imputed righteousness unto him, and through him all the families of the earth would be blessed. Our position is thus tied to believing God as Abraham did.
Les explains that Paul's stipulation carries from Abraham's faith all the way to where we are: as Abraham believed God, so is where we are. He notes that faith was what imputed righteousness unto Abraham, and that through him all the families of the earth would be blessed. Les then moves to Genesis 3, where God promises a Redeemer through the woman—the seed who is Christ—and shows the Abrahamic covenant is built on that promise: through this man and his offspring the seed of the woman would come.
